fix: `HEAD` may now return itself as prefix in `RefSpecRef::prefix()` and `expanded_prefix()`. (#450)

Previously, the expanded prefix would be a list of possibilities, even though it's such a common case that we really want to avoid spamming the remote about it when asking for HEAD during clone for instance.
